Change the binary names of curl and libcurl as part of the curl build
process by patching curl's build scripts. When running 'make' in the
patched curl directory the resulting binaries will be already named
'curl-impersonate-ff' and 'curl-impersonate-chrome' (and the same for
libcurl), thus saving the need for manually renaming them after the
compilation. This also enables running 'make install' with curl's own
Makefiles in order to install curl-impersonate.
Add support for impersonating Chrome 99 on Android 12 (Pixel 6 was
chosen as an arbitrary Android phone to impersonate). The TLS signature
for Chrome on Android is identical to Chrome on Windows. The difference
is in a few HTTP headers ('sec-ch-ua-mobile', 'sec-ch-ua-platform' and
'user-agent').
Add the ability to control the order of the HTTP/2 pseudo-headers. Each
browser uses a different order for the ":method", ":authority",
":scheme" and ":path" pseudo-headers. It is therefore desirable to be
able to control it. The CURLOPT_HTTP2_PSEUDO_HEADERS_ORDER libcurl
option and '--http2-pseudo-headers-order' command line option now allow
doing that.

A previous commit has enabled the TLS session ticket extension (by
removing SSL_OP_NO_TICKET) because Chrome uses it. This commit makes it
configurable via the CURLOPT_SSL_ENABLE_TICKET libcurl option or the
'--tls-session-ticker' command line flag. The goal is to impersonate
Safari which, as of version 15.3, does not use TLS session tickets.
This commit adds:
* Support for configuring the TLS certificate compression algorithms the
client is willing to receive via the CURLOPT_SSL_CERT_COMPRESSION option or
the '--cert-compression' command line flag.
* Support for decompressing zlib-compressed certificates in addition to
brotli.
Previously brotli decompression only was available and it was hardcoded
into the binary.
This commit makes some of the TLS options that are used for
impersonation configurable via libcurl options and command line flags to
curl-impersonate. The goal is to give more flexibility in configuring
the TLS extensions instead of hardcoding everything into the binary.
This will enable using the same binary for impersonating different
browsers (e.g. Safari).
The following options are now present:
* CURLOPT_SSL_EC_CURVES and the '--curves' flag are now usable. These
were present in the upstream curl but only for OpenSSL builds. This
commit also enables them for BoringSSL. They configure TLS extension
'supported_groups' (no. 10).
* CURLOPT_SSL_ENABLE_NPN and the '--no-npn' flags are usable. These were
present in the upstream curl but were disabled in a previous commit by
commenting out the relevant code (as Chrome disables NPN). They now work
and the wrapper scripts use the '--no-npn' flag.
* CURLOPT_SSL_ENABLE_ALPS and the '--alps' flag were added. These
control the ALPS TLS extension that Chrome uses.
* CURLOPT_SSL_SIG_HASH_ALGS and the '--signature-hashes' option were
added. These control the clien't list of supported signature & hash
algorithms, i.e. TLS extension 'signature_algorithms' (no. 13).
Patch generated from https://github.com/lwthiker/curl/commit/e8cd43c8ebd2624b3c635ec96b165c28f675cdf2
Add curl_easy_impersonate() API function that sets the needed options
on the curl 'easy' handle. It sets the various TLS options needed for
impersonation and the HTTP headers that the browser sends by default.
In addition, libcurl will check for the environment variable
CURL_IMPERSONATE when curl_easy_init() is called, and if it exists it
will call curl_easy_impersonate() internally. This theoretically allows
replacing an existing libcurl by setting the LD_LIBRARY_PATH and
CURL_IMPERSONATE env vars, without having to recompile the app.
Consolidate all of curl's patch files into a single file (one for each
browser). The modified curl source code is now maintained in Git (at
https://github.com/lwthiker/curl) and it is easier to just
generate the needed patch with 'git --diff'.
